I just realized that the title return of the jedi could be refer to vader becoming anakin skywalker again.

I like it!

Of course the original title was "Revenge of the Jedi"
Was changed as the PR people thought having Revenge in the title was a bit too aggressive for some bizarre reason...

It was changed because Lucas said Jedi don't take revenge. Those original posters are worth a little money as well.

I know.
I was at a convention shortly before it released. At the time my buddy and I knew the title was going to change. There was a lot of "Revenge of the Jedi" merchandise available. We passed on that (like non mental giants) as we thought the Return stuff would be better LoL.

I don't get the title the last Jedi when return of the Jedi means their return after the fall of the empire and the new movies should of focus on Luke's students. So Kylo took over half of Luke's students so Ren and 6 others leaving 5 other Jedi that they killed. So what happen in those 30 years Luke trained zero? No I say he trained maybe 24 students in those 30 years. So the Jedi had returned. And the last Jedi title in it self makes no since. Can we honestly say Ren was trained well enough to hunt all of them down? Nope we can't. Even if Snoke finished his training which we all know he did not by the lack of confidence in Ren. Ren is not the leader or the talent of such great Sith and Jedi of days gone. He is too conflicted. Even anikin as good as he was was conflicted and took out by Kenobi the drinking least of the Jedi masters! And Luke was greater than kenobi. So the title Return of the Jedi suggest that their are more than Luke at the end of the film and other Jedi came out of hiding. Which means the title the last Jedi is the last Jedi trained by Luke which is the story of Kylo Ren not Rey. And I bet one or two of Luke's students made it out and will want revenge for their master. Or the return of the Jedi's original title Revenge of the Jedi.

I just realized that the title return of the jedi could be refer to vader becoming anakin skywalker again.

I also realized that the phantom menace refers to Sidious being “the phantom menace”

And that Attack of The Clones is where the clones attack!

And that Revegne of the sith is where the sith have their revenge!

And the new hope is where the rebellion gets a “A new hope”!

And the empire strikes back is where the empire strikes back!

And the force awakens is where Rey wakes up!

And the Last Jedi is where Luke says he’s “The Last Jedi”!

Shall I go on?

Given that you have done a great job of taking the other titles absolutely literally, I don't understand why you didn't get that 'The Force Awakens' is where the 'Force' itself wakes up. Rey is the catalyst. We find out in 'The Last Jedi' that Luke has cut himself off from the force and arguably the dark side is more about manipulating the force than awakening it.

Rey comes into contact with Luke's LIghtsabre and suddenly the force is alive again.
